Overview

This project implements a Model Context Protocol (MCP) server that exposes three powerful tools for analyzing trading activity on Polymarket. It combines real-time leaderboard data from Polymarket's Data API with LLM-powered strategy classification via OpenAI.

Key Features

• 🏆 Top Trader Discovery — Fetch leaderboard rankings by timeframe
• 🧠 AI Strategy Analysis — Classify strategies (arbitrage, market-making, etc.) using GPT-4o-mini
• 🤖 Bot Detection — Heuristic + LLM-based identification of automated traders
• 📊 Batch Reporting — Concurrent analysis of multiple profiles
• 🔄 Resilient API Layer — Exponential backoff, rate-limit handling (429 + Retry-After), graceful fallbacks

Tools

1. find_top_traders

Fetch top-performing traders from the Polymarket leaderboard with bot detection.

Parameter	Type	Description
limit	integer	Number of traders (1–50)
timeframe	string	"7d", "30d", or "all_time"

Output: Array<{ profile_id, pnl, is_bot }>

2. analyze_trader_strategy

Deep-dive analysis of a single trader using trade history + LLM classification.

Parameter	Type	Description
profile_id	string	Wallet address (0x…) or username (@name)

Output: { strategy_description, risk_level, risk_justification, success_score, is_bot }

3. generate_batch_report

Concurrent analysis of multiple profiles with error-resilient execution.

Parameter	Type	Description
profile_ids	string[]	Array of profile IDs (1–50)

Output: Array<{ profile_id, pnl, strategy_description, risk_level, risk_justification, success_score, is_bot }>

Getting Started

Prerequisites

• Node.js ≥ 22
• npm ≥ 10
• OpenAI API key (for strategy analysis)

Installation

# Clone the repository
git clone <your-repo-url>
cd polymarket-mcp-bot-analyst

# Install dependencies
npm install

# Configure environment
cp .env.example .env
# Edit .env and add your OPENAI_API_KEY

Build & Run

# Build TypeScript
npm run build

# Start the MCP server (stdio transport)
npm start

# Or run directly with tsx (development)
npm run dev

---

Connect to Claude Desktop

Add this server to your Claude Desktop configuration:

macOS

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "polymarket-bot-analyst": {
      "command": "node",
      "args": ["/absolute/path/to/polymarket-mcp-bot-analyst/dist/index.js"],
      "env": {
        "OPENAI_API_KEY": "sk-..."
      }
    }
  }
}

Windows

Edit %APPDATA%\Claude\claude_desktop_config.json:

{
  "mcpServers": {
    "polymarket-bot-analyst": {
      "command": "node",
      "args": ["C:\\path\\to\\polymarket-mcp-bot-analyst\\dist\\index.js"],
      "env": {
        "OPENAI_API_KEY": "sk-..."
      }
    }
  }
}

After saving, restart Claude Desktop. The three tools will appear in the tools menu (🔨 icon).

Run the Test Suite

The test runner executes all three tools against the live Polymarket API and generates the required JSON artifacts:

npm run test:run

This produces:

File	Description
test_run.json	Full execution log with data for 3+ traders
performance_report.json	Latency metrics for each endpoint
my_report.json	Architectural description of each endpoint
